Current optical disorder (7)

I believe the answer is:

topical

'current' is the definition.
(similar in meaning)

'optical disorder' is the wordplay.
'disorder' indicates anagramming the letters (a disordered version of the letters).
'optical' anagrammed gives 'TOPICAL'.

(Other definitions for topical that I've seen before include "About current events in Capitol" , "Like The Sunday Times" , "Having reference to current events" , "Relating to current affairs" , "hot" .)

I've seen this clue in The Globe and Mail.
